Welcome on board, Lachlan. It's always nice to see more Aussies on the Forum.As the Dr. says, some more details about the aging would help to work out what is going on, also details about the make and what the problem is with the cheese.I would suggest that you look at posts from a variety of people to see how they record their processes. Keeping good records is very important in diagnosing problems but also for replicating your successes. (Just between you and me, my records could sometimes be better.)
